Sum rules start from the definitions of the interpolating currents
for involved hadrons. The following currents are respectively adopted
for \(\Xi _{c}\)  and \(\Xi \)  [1]}
\(J_{\Xi _{Q}} & =\epsilon _{abc}(q_{a}^{T}C\gamma _{5}s_{b})Q_{c},\nonumber \\J_{\Xi } & =\epsilon _{abc}(s_{a}^{T}C\gamma ^{\mu }s_{b})\gamma _{\mu }\gamma _{5}q_{c},\)
